-  version: "1.22"
+  # For reference, this is the steps I took when upgrading from k8s 1.22 to k8s
+  # 1.24, Dec 18th 2022.
+  #
+  # 1. Performed step 1-7 from above to, but migrated control plane from 1.22 to
+  #    1.23 and node groups from 1.22 to 1.24.
+  #
+  # 2. When performing step 7:
+  #
+  #    - the aws-node daemonset's pods failed to start because of a too
+  #      restrictive container securityContext not running as root.
+  #    - the kube-proxy deamonset's pods failed to pull the image, it was not
+  #      found.
+  #
+  #    I patched the aws-node thing now, but went ahead with the upgrade to k8s
+  #    1.24 in the control plane, hoping another `eksctl utils update-aws-node`
+  #    and `eksctl utils update-kube-proxy` would resolve the issues.
+  #
+  #    Later I concluded the following:
+  #
+  #    - aws-node issue: https://github.com/weaveworks/eksctl/issues/6048.
+  #      Resolved by removing `runAsNonRoot: true` and
+  #      `allowPrivilegeEscalation: false`.
+  #    - kube-proxy issue: it went away when upgrading the plugin in 1.24
+  #    - the cluster-autoscaler failed to start initially, but made it in the
+  #      end when other pods got running.
+  #
+  # 3. I upgraded the control plan to 1.24 (step 2 above) and re-upgraded add-ons
+  #    (step 7 above).
+  #
+  # 4. I recreated all node groups as in step E above.
+  #
+  # 5. My hub pod entered a pending state because
+  #
+  #    - 1 node(s) had no available volume zone
+  #    - I think this is the issue:
+  #      https://docs.aws.amazon.com/eks/latest/userguide/ebs-csi.html, I
+  #      upgraded from v1.22 to v1.23+ without manually activating the plugin
+  #      mentioned there.
+  #    - Looking at
+  #      https://docs.aws.amazon.com/eks/latest/userguide/managing-ebs-csi.html
+  #      and running the command below, I conclude it was not active in my
+  #      cluster.
+  #
+  # 6. (what I should have done) Getting ebs-csi-driver setup:
+  #
+  #    What I think should have been done is to:
+  #
+  #    1. Ensure a service account was setup via this config:
+  #       https://eksctl.io/usage/schema/#iam-serviceAccounts-wellKnownPolicies-ebsCSIController
+  #    2. Ensure that the addon was setup via this config:
+  #       https://eksctl.io/usage/schema/#addons-wellKnownPolicies-ebsCSIController
+  #    3. Ensure that the node pools using ebs storage (core) was configured to use this:
+  #       https://eksctl.io/usage/schema/#nodeGroups-iam-withAddonPolicies-ebs
+  #
+  # 6. (what I actually did) Getting ebs-csi-driver setup:
+  #
+  #   I read the following instructions: https://docs.aws.amazon.com/eks/latest/userguide/managing-ebs-csi.html#adding-ebs-csi-eks-add-on
+  #
+  #   I did pre-requisites to setup permissions via: https://docs.aws.amazon.com/eks/latest/userguide/csi-iam-role.html
+  #
+  #     UPDATE: I think this pre-requites step could be done via this config instead:
+  #             https://eksctl.io/usage/schema/#iam-serviceAccounts-wellKnownPolicies-ebsCSIController
+  #
+  #     eksctl get addon --name aws-ebs-csi-driver --cluster=jmte
+  #
+  #     eksctl create iamserviceaccount \
+  #         --name=ebs-csi-controller-sa \
+  #         --namespace=kube-system \
+  #         --cluster=jmte \
+  #         --attach-policy-arn=arn:aws:iam::aws:policy/service-role/AmazonEBSCSIDriverPolicy \
+  #         --approve \
+  #         --role-only \
+  #         --role-name=AmazonEKS_EBS_CSI_DriverRole
+  #
+  #   I verified I didn't have a EBS driver installed already:
+  #
+  #     eksctl get addon --name=aws-ebs-csi-driver --cluster=jmte
+  #
+  #   I added the ebs driver addon:
+  #
+  #     UPDATE: I think this main step could be done via this config instead:
+  #             https://eksctl.io/usage/schema/#addons-wellKnownPolicies-ebsCSIController
+  #
+  #     eksctl create addon --name=aws-ebs-csi-driver --cluster=jmte --service-account-role-arn=arn:aws:iam::286354552638:role/AmazonEKS_EBS_CSI_DriverRole --force
+  #
+  #   The hub pod that mounted a PVC with ebs storage and got "1 node(s) had no
+  #   available volume zone" was suddenly scheduled successfully!
+  #
+  #   I think maybe we could manage to setup eksctl clusters to directly have
+  #   this plugin via this config. For now, this was done with manual patches
+  #   though.
+  #
